I enjoy the reflection, but the composition needs a lot of work.
A great rule of thumb if you're going to shoot a whole figure like you have here is give it space in the photo. You've just nearly cut his head off, which can turn off the viewer visually. For the future, make sure you always leave yourself enough space to crop the photo later on.
As a fix for this picture, I would suggest you make this a square photo to get rid of the large blurry section at the bottom of the frame.
